$test = "{$a}{$b}";
$test = "{$a} {$b}";
$a = "foo $(bar7) $1";
$string = "Hello World";
settype($foo , "Bool");
log("Data: {$data}");
// Ignored because it contains non-strings
$this->createError('Error: ' . $error->getMessage('Extra data') . PHP_EOL);
echo inverse(0) . "\n";
// Ignored because it is multiline
echo "This is a very long string that contains
newlines" . "End of string";
// Ignored because it contains double quotes
echo "This is a very long string that contains \"double quotes\"" . "End of string";- Examples of incorrect code for this rule using default options
